The recommended amount of pregnancy weight gain is related to the body weight of the expectant mother before pregnancy. As the body mass index (BMI) increases, the amount of weight to be gained decreases.

BMI is calculated by dividing the body weight in kilograms by the height in metres squared. The unit of BMI is kg/m².
